Detailed Description

The base class for classes which update a single link table.

A LinksTable object is a container for new and existing link sets outbound from a single page, and an abstraction of the associated DB schema. The object stores state related to an update of the outbound links of a page.

Explanation of link ID concept

Link IDs identify a link in the new or old state, or in the change arrays. They are opaque to the base class and are type-hinted here as mixed.

Conventionally, the link ID is string|string[] and contains the link target fields.

The link ID should contain enough information so that the base class can tell whether an existing link is in the new set, or vice versa, for the purposes of incremental updates. If a change to a field would cause a DB update, the field should be in the link ID.

For example, a change to cl_timestamp does not trigger an update, so cl_timestamp is not in the link ID.

Stability: stable: to extend

Member Function Documentation

◆ beforeLock()

MediaWiki\Deferred\LinksUpdate\LinksTable::beforeLock ( )

Subclasses can override this to do any necessary setup before the lock is acquired.

Stability: stable: to override

Definition at line 428 of file LinksTable.php.

◆ deleteLink()

MediaWiki\Deferred\LinksUpdate\LinksTable::deleteLink ( $linkId )

abstractprotected

Delete a link identified by ID.

The subclass is expected to queue the deletion by calling deleteRow().

Parameters

mixed $linkId

Reimplemented in MediaWiki\Deferred\LinksUpdate\CategoryLinksTable, MediaWiki\Deferred\LinksUpdate\ExternalLinksTable, MediaWiki\Deferred\LinksUpdate\GenericPageLinksTable, MediaWiki\Deferred\LinksUpdate\ImageLinksTable, MediaWiki\Deferred\LinksUpdate\InterwikiLinksTable, MediaWiki\Deferred\LinksUpdate\LangLinksTable, and MediaWiki\Deferred\LinksUpdate\PagePropsTable.

◆ deleteRow()

MediaWiki\Deferred\LinksUpdate\LinksTable::deleteRow ( $conds )

protected

Queue a deletion operation.

Subclasses are expected to call this from deleteLink(). The "from" field does not need to be included in the conditions.

Most often, the conditions match a single row, but this is not required.

Parameters

array $conds Associative array mapping fields to values, specifying the conditions for a delete query.
